Body and fender work refers to the repair, restoration, and maintenance of a vehicle's outer body and structural components. It typically involves fixing dents, scratches, rust, and other damage to the body panels, as well as repairing or replacing fenders (the parts surrounding the wheels). Technicians skilled in body and fender work use various tools and techniques like welding, sanding, and painting to restore the vehicle to its original appearance and function. This type of work is common in auto body shops and is essential after accidents or wear and tear.
